Girls, hello ?? I previously had pain and compression of the sciatic nerve in my right leg. Now I have this pain much stronger but in my left leg? The right one doesn't hurt anymore, but the left one pulls and the knees are unbearable???? Tried massage, it didn't help much, straight if you can't stand it then you drink ibuprofen after half an hour it works. But after it stops working, terrible pain starts??? Don't know what to do, what should I do? Now I want to try nimesil. Pregnancy 34 weeks.
